I'm attempting to monitor a pair of arrays running 8.1.4 7-Mode. The poller reports the follwoing in the log file:

Any ideas?

Hi,

The Data ONTAP API interface packages uses XML and from this error there was a failure to parse some response. I suspect some kind of network failure caused the XML document to get truncated which resulted in a failure to parse it and that error. If you see it often I would suspect network errors or instability in the network are to blame.

Maybe you can take a packet trace or use other network troubleshooting techniques to research deeper?
